I think you may have your terminology mixed up...or I'm just confused because of a lack of coffee so far today.
Are you referring to the wort when talking about dumping it into your carboys? You wouldn't dump the mash in, you would mash out and drain the wort out of the grains to boil. Then...
Has anyone heard anything else about this? I entered but have not actually heard from Triumph and/or Preston and Steve about all the brews being accepted. Just wonderin'....
I used a high density weather stripping and cut it. It's joined at the corners with a fairly tight seal. I also squeezed a little caulk in there just to make sure there were no leaks. I also used liquid nails to glue it down because it wasn't sticking too well. Hope that helps!
